9.6.7 Download New Site Data (RS, LD, CN and DS)
13) 9.6.7 Download the site data into the MOVA unit from the PC and then
clear the MOVA working data as instructed on the screen (only
available from PB681 issue 10 onwards).
Caution: If the new site data contains a different number of links, lanes or stages, or
different time-of-day data then MOVA must be re-initialised. Only if the configuration
is the same as the configuration currently running in the MOVA unit (except for minor
changes to timing values), can the new site data be downloaded without initialising
the unit.
Prior to issue 10, this meant that the I/O cables at the back of the unit MUST be
disconnected while the unit is initialised and the new data loaded. This ensures that
the MOVA unit is not monitoring the junction while running its default data set. When
the new data has been loaded, the I/O cables can be reconnected. With later issues
of firmware, MOVA can be re-initialised after the new site data has been loaded so
the I/O cables do not need to be disconnected.
New site data can be downloaded into the MOVA unit using the ‘Read in Site data’
option – ‘RS’ from the MOVA main menu.
This option is password protected to prevent unauthorised changes to the site data
and can only be attempted locally. The password is case sensitive and is defaulted
to ‘AVOMGO’.
Up to three ‘plans’ can be loaded into the MOVA unit’s memory. Normally, only plan
1 will be used. However, it is possible to configure the MOVA unit to switch between
the plans at different times of day, hence up to three plans, numbered 1 to 3 may
have to be downloaded.
No time of day changes – If only one plan is to be downloaded, then the site data file
name is usually suffixed by the ‘.PT’ extension. Enter the name of site data file
without the ‘.PT’ extension and when asked, select plan number ‘1’. When loading is
complete, the MOVA unit will recognise that this plan data contains no time of day
changes and will not require any more plans to be downloaded.
Three plans – When the site data contains time of day changes, each plan has to be
downloaded into the MOVA unit one after the other. Enter the name of site data file
without the extension and the three plans should be listed on the screen, e.g.
Enter the name of the file without any extension
(or QUIT to abort) ... E12345
1. E12345.P1
2. E12345.P2
3. E12345.P3
key number of the file you wish to transmit . . .
Start with plan 1, and download the site data with the extension ‘.P1’. When that data
has been loaded, the MOVA unit will insist that two more plans be downloaded so
